[0002] Wastewater is polluted water generated in production and daily life, containing various impurities and pollutants. Wastewater treatment pump stations are key facilities in wastewater treatment systems. Their main function is to raise the water level of wastewater through pumps and transport it from the collection point to the subsequent treatment unit. They are the power hub for wastewater flow. In wastewater treatment pump stations, wastewater often contains impurities such as solid particles, fibers, and debris. If these impurities directly enter the pumps, they will cause pump blockage, impeller wear, or even equipment failure and shutdown, affecting the continuity of the entire wastewater treatment process. Therefore, filtration devices are an indispensable part of the pump station.

[0003] However, existing filtration devices are not convenient for squeezing out the filtered impurities during use, resulting in impurities with high moisture content and large volume. This not only increases the difficulty of subsequent transportation and processing, but also occupies more storage space. Furthermore, the residual moisture in the impurities can carry pollutants, causing secondary pollution. Utility Model Content

[0027] The extrusion section 2 includes an extrusion assembly 21 mounted on the filter cylinder 111; and a scraping assembly 22 mounted on the extrusion assembly 21. The extrusion assembly 21 includes a first rotating shaft 211 rotatably connected to the inner wall of the bottom of the filter cylinder 111, the bottom of the first rotating shaft 211 extending outside the filter cylinder 111, a protective shell 212 fixedly connected to the outer wall of the first rotating shaft 211, and a second rotating shaft 213 rotatably connected to the inner wall of the protective shell 212. 3. The side away from the first rotating shaft 211 extends to the outside of the protective shell 212. A squeeze roller 214 is fixedly connected to the outer wall of the second rotating shaft 213. A transmission component is provided above the filter plate 112. The squeeze roller 214 is located above the filter plate 112. The scraping assembly 22 includes an L-shaped connecting rod 221 fixedly connected to the outer wall of the first rotating shaft 211. A scraper 222 is fixedly connected to the side of the L-shaped connecting rod 221 away from the first rotating shaft 211. A guide is provided on the inner wall of the filter cylinder 111. The filter housing 211 is a series of components. The scraper 222 has its bottom contacting the top of the filter plate 112. A transmission component includes a conical tooth 215 fixedly connected to the top of the filter plate 112. A rotating shaft 211 has its top penetrating the conical tooth 215.

Both the conical tooth 215 and the conical tooth 216 are located within the protective shell 212. A flow guide includes a flow guide plate 223 fixedly connected to the inner wall of the filter cylinder 111. The flow guide plate 223 is inclined. By setting the extrusion section 2, the extrusion roller 214 can be driven by the motor 311 to both revolve and rotate, effectively extruding the filtered impurities, reducing their moisture content and volume. Simultaneously, the scraper 222 scrapes the impurities back up for further extrusion, reducing the difficulty of subsequent transportation and processing, saving storage space, and reducing secondary pollution caused by residual moisture in the impurities carrying pollutants, thus improving the practicality and environmental friendliness of the filtration device.

[0028] The filtration unit 3 includes a motor 311 fixedly connected to the bottom of the filter cylinder 111.

[0029] One specific application of this embodiment is as follows: In use, the wastewater to be filtered is first poured into the filter cylinder 111. The wastewater falls onto the filter plate 112, where it undergoes preliminary filtration. Due to the guidance of the guide plate 223, the wastewater is more easily concentrated in the working area of ​​the squeeze roller 214. When pouring the wastewater, the motor 311 can be started to drive the rotating shaft 211 to rotate. At this time, the protective shell 212 drives the squeeze roller 214 on the rotating shaft 213 to rotate around the rotating shaft 211. During this process... Due to the interaction between conical teeth 216 and 215, the extrusion roller 214 will also rotate to extrude impurities on the top of the filter plate 112. The extruded impurities will be scraped up again by the scraper 222 on the L-shaped connecting rod 221. When the rotating shaft 211 rotates, the rotating shaft 211 will also drive several housings 313 to rotate around the rotating shaft 211 through the connecting rod 312. During this process, the activated carbon in the housings 313 will further filter the wastewater that has been initially filtered by the filter plate 112.
